Module Name:    src
Committed By:   dyoung

Modified Files:
        src/lib/libc/net: getifaddrs.c
        src/sbin/ifconfig: util.c

Log Message:
Bring getifaddrs(3) behavior in line with the documentation: the
ifa_data member of every AF_LINK struct ifaddrs points at the
corresponding struct if_data.  In ifconfig(8), do not try to suppress
duplicate AF_LINK ifaddrs by checking for a NULL ifa_data.

Don't copy out two AF_LINK struct ifaddrs for each active link-layer
address. getifaddrs(3) used to copy out one ifaddrs for the kernel's
RTM_IFINFO message, and one more for the kernel's RTM_NEWADDR message.
I suppress the first duplicate with a highly conservative change that
wastes a little bit of ifaddrs storage.  The storage is not leaked.
